Scope
This standard specifies the terminology and definitions, symbols and units, general rules, test preparations, test requirements, measurement items and test instrumentation, test methods, calculation of thermal efficiency of boilers, and test reports in the thermal performance tests of industrial boilers.
This standard applies to the thermal performance tests of solid fuel boilers, liquid fuel boilers, gas fueled boilers and electric heating boilers whose rated pressure is less than 3.8 MPa and whose medium is water or liquid organic heat carrier.
Oil-fired steam boilers, waste heat utilization devices or equipment (except flue type waste heat boilers), boilers with a steam pressure of not less than 3.8 MPa and a steam temperature of less than 450°C can be used as reference.

3 Terms and Definitions
The definitions of GB/T 2900.48 and the following terms and definitions apply to this document.
3.1
Solid fuel solidfuel
Solid fuels, including coal, oil shale, biomass fuels, and combustible solid waste
3.2
Liquid fuel
Liquid fuels, including petroleum, fuel oils, and industrial waste fluids (such as lye, magnesium, etc.)
3.3
Gas fuel gasfuel
Gaseous fuels include natural gas, blast furnace gas, coke oven gas, city gas, and liquefied gas
3.4
Low calorific value
The quantity of heat released from the complete combustion of a unit volume of gaseous fuel or unit mass of solid or liquid fuel under certain conditions, minus the latent heat of vaporization of water vapour in the flue gas
.
3.5
Heat output
The difference between the amount of heat that is provided by steam, water, or other working fluid from the boiler outside and the water or other working fluid that enters the boiler
3.6
Net boiler efficiency
The boiler effectively uses heat to deduct boiler efficiency after self-use steam and auxiliary equipment consume power to convert heat.
3.7
Positive balance method
The method of directly measuring the input heat and output heat to determine the thermal efficiency of the boiler is also called a direct measurement method or an input-output method
